i already orderd 225/45/17....those were the biggest sidewalls that fit the 9-3s i think. I was gonna go 235/40/17 but the sidewall is a litlle smaller than the 215/45. They are BFGoodrich T/A KDW
People might think they look stupid...but i really dont care. i think they look cool but the main reason i got them is cause they have 300 treadwear rating, and they got amazing reviews, and price of course.
